My website hung up for almost 24 hours (over a weekend) because a variable called Maxclients reached the maximum allowable level. The logs showed the following issue occurring at about the same time (I am not saying that this error is the culprit... there were several errors in the error log.)

My sql error log show things like:

which makes little sense to me.
Is this sort of thing a normal occurrance? How should I proceed to figure out what is going on?

The forum could not connect to MySQL, the culprit was the mysql_connect() function that failed. It is possible that at the time MySQL server was down or was @ maximum allowed connections and was rejecting further connections.

Along the same lines, the following set or series of errors seems to be running wild. Am I doing something wrong? I had made a change in order to put a SSI text (site navigation) file alongside the forum. Now as I look into the error log, it appears to need some additional information.

What you are seeing are actually PHP errors inside PHP function readfile, this is not a forum bug.

The hint was given that it (the PHP Warning) may be a permissions issue. I changed the forum folder from 755 to 775, and, perhaps coincidentally, the error seems to have stopped happening. Question: Am I ok to leave the forum folder at 775?

It is the main forum folder, the one that contains index.php. But I may have answered my own question in that I left it at 775 overnight, and I still got a slew of readfile messages the next morning. Now I am wondering if it can be related to my traffic limit of ten processes.

that is a very likely reason, if you are requesting files from a web server which is limited to just 10 processes you can easily reach the limit of apache processes.
